The HEF4541B is a versatile programmable timer IC from Philips, designed for timing and frequency division applications. It integrates a 16-stage binary counter and an oscillator circuit that can be configured with external components (Rt and Ct) to operate within a frequency range of 1 Hz to 100 kHz. The device also supports an external clock signal input.
Key features include automatic power-on reset and output control logic. The counter's frequency division ratio can be set to 2^8, 2^10, 2^13, or 2^16, depending on the state of the address inputs (A0, A1). The timer can function as a single transition timer or a frequency divider based on the MODE select input.
This specific part, the HEF4541BT, is supplied in a 14-lead SO (Surface Mount) package, suitable for standard PCB assembly processes. It is part of the MSI (Medium Scale Integration) family of integrated circuits.
Applications for the HEF4541B include pulse generation, waveform shaping, and general-purpose timing circuits where precise frequency division or timed outputs are required.
